A WARNING
You or your passengers could be injured
while changing a wheel if you do not fol­
low these safety precautions:
- If you have a flat tire, move a safe dis­
tance off the road. Turn off the engine,
turn the emergency flashers on and use
other warning devices to alert other mo­
torists.
- Make sure that passengers wait in a safe
place away from the vehicle and well
away from the road and traffic.
- To help prevent the vehicle from moving
suddenly and possibly slipping off the
jack, always fully set the parking brake
and block the wheel diagonally opposite
the wheel being changed with the fold­
ing chocks or other objects. When one
front wheel is lifted off the ground, plac­ ing the Automatic Transmission in "P"
(Park) will
not prevent the vehicle from
moving .
- Before you change a wheel, be sure the
ground is level and firm. If necessary,
use a sturdy board under the jack.
- Always store the vehicle tool kit, the
jack* and the replaced tire in the luggage compartment
¢page 133.
(D Note
If you are changing the wheel on a steep
incline, use a rock or similar object to
block the opposite wheel to prevent the
vehicle from moving.

There is exactly one location for each wheel.
The jack must not be positioned at any other locat ion
c:> ,&. c:>(D .
Soft ground under the jack can cause the ve­
h icle to slip off the jack. Always place the jack
on firm ground. Use a flat, stable support if necessary . Use a non-slip surface such as a
rubber mat on a
slipp ery surfac e such as tile .
A WARNING
-You or your passengers could be injured
wh ile chang ing a wheel if you do not fol­
low these safety precautions :
- Position the vehicle jack only at the
des ignated lifting points and align the
jack. Otherwise, the vehicle jack could slip and cause an inj ury if it does not
have sufficient hold on t he veh icle .
- A soft or u nstab le surface under the
jack may cause the veh icle to slip off
the jack . A lways provide a firm base for
the jack on the ground.
If necessary,
use a sturdy boa rd un der the jac k.
- On hard, slippery surfac e (such as til es)
use a rubbe r mat o r similar to preven t
the jack from s lipping.
- T o help p revent injury to yourself and
yo ur p assenge rs: -
Do not raise the vehicle until you are
sure the jack is securely engaged.
- Passengers must not remain in the ve­
hicle when it is jacked up.

Bulbs
Replacing bulbs
For your safety, we recommend that you have
your authorized Audi dealer replace any bulbs for you.
It is becoming increasingly more and more
difficult to replace vehicle light bulbs since in many cases, other parts of the car must first
be removed before you are able to get to the
bu lb. Thi s applies especially to the light bu lbs
in the front of your car which you can only
reach through the engine compartment .
Sheet metal and bulb holders can have sharp
edges that can cause ser ious cuts, parts must
be correctly taken apart and then properly put
back together to help prevent breakage of
parts and long term damage from water that
can enter housings that have not been proper·
ly resealed.
F or your safety, we recommend that you have
your author ized Audi dealer replace any bulbs
for you, since your dealer has the proper tools,
the correct bu lbs and the expertise.
Ga s discharge lamps (Xenon lights}*:
Due to the high electrical vo ltage, have the
bu lbs rep laced by a qualified technician.
H eadlights with Xenon l ight are identified by
the high voltage sticker.
A WARNING
Changing Xenon lamps without the neces­
sary equipment can cause serious personal
in jury.
- Bulbs are pressurized and can explode
when being changed. Potential risk of in­
jury!
- On vehicles equipped with gas discharge
bulbs (Xenon light)* life-threatening in­
juries can result from improper handling
of the high-voltage portions of such
lamps!
- Only your authorized Audi dealer or a
qualified workshop should change the
bu lbs in gas discharge lamps. There are
pa rts with sharp edges on the openings
and on the bulb holders that can cause
serious cuts. If you are uncertain about
what to do, have the work performed by
an author ized Audi dealer or other quali­
fied workshop. Ser ious personal injury
may result from improperly performed
work.
(D Tips
- If you st ill prefer to replace the light
bulbs yourself, be aware that the engine
compartment is a hazardous area to
work in
9 page 213, Engine compart­
ment
9 Lr:,. .
-It is best to ask your authorized Audi
dealer whenever you want to change a
bulb.
